I host a website that uses mTLS for authentication. I created a client cert and installed it in Firefox on Linux, and when I visit the site for the first time, Firefox asks me to choose my cert and then I'm able to visit the site (and every subsequent visit to the site is successful without having to select the cert each time). This is all good.

But when I install that client cert into GrapheneOS (settings -> encryption & credentials -> install a certificate -> vpn & app user certificate), no browser app seems to recognize that it exists at all. Visiting the website from Vanadium, Fennec, or Mull browsers all return "ERR_BAD_SSL_CLIENT_AUTH_CERT" errors.

Does anyone have experience successfully using an mTLS cert in GrapheneOS?

[SOLVED] Thanks for the solution, @Evkob@lemmy.ca

I got a new printer. Auto-discovered, added, and prints fine from Windows in 2 minutes. Auto discovered, added, and prints fine from OSX in 30 seconds. Auto-discovered and added on Linux, but trying to print results in "printer is unreachable at this time" - even after 50 re-installs, different configs, different drivers, different protocols.

I recognized that some computers were on different subnets, but couldn't figure out a pattern. It turns out that the printer has a setting called "Restricted Server List" and the default setting is null. Here's its description in the admin interface: "Comma-delimited list of IP addresses that are allowed to make TCP connections. Example: 157.184.0.0/24. where 0 is a wildcard and /24 is the network prefix."

It also has a setting called "Restricted Server List Options", set to block all ports by default. Here's its description: "By default, addresses not in the restricted server list will have all access blocked. When Block Printing Only is selected, addresses not in the restricted sever list will be blocked from printing only. When Block Printing and HTTP Only is selected, addresses not in the restricted server list will be blocked from printing and HTTP. "

Admin interface doesn't say this anywhere, but the default setting of no restricted servers apparently allows access from other networks, but not from the same network as the printer. I set the restricted servers to "192.168.132.0/24" and then I could access the printer admin web page and print to the printer from my Linux box, but not from any of the computers that were working before. So I set it to "192.168.0.0/16" and every computer on all subnets in my house can print and access the printer admin.

The default setting of no restricted servers was extremely non-intuitive in that it actually only restricted servers on the same subnet. And there was no such documentation.

What a crappy waste of 7 frickin' hours!

I understand that if you have Bitwarden (or any password manager or browser) configured to autofill your password when it encounters a "password" field on a web form, an easy exploit is for the web form to have hidden form fields (e.g., address, phone, email, ssn) and your autofill app will fill in your info into those fields, even though you only wanted it to autofill the login.

But when you have autofill turned off and you click in a form's "login" field and select a login from Bitwrden's contextual menu, Bitwarden automatically also fills in the "Password" field. Does this mean that the exploit exists even if autofill is turned off, as long as you're using any form of an "auto-fill" function?

Thanks to Smart Home Junkie's video (invidious link), I had my Atom Echos as voice recognition boxes with all audio output redirected to a media player of my choice (because the audio on the Echo is super quiet).

Whenever ESPHome updated, I updated my Echos to get the recent ESPHome updates, and then reinstalled the custom yaml for audio redirection.

However, with ESPHome's recent 2024.6.4 update, trying to install the yaml triggers errors that don't seem to make sense. For example, here's a section of the yaml:

On lines 3 and 10 I define unique IDs for the device's microphone and speaker.

But ESPHome won't compile, telling me:

• on line 46: Too many candidates found for 'id' type 'speaker::Speaker' Some are 'echo_speaker', 'echo_speaker_kitchen'.
• on line 57: Too many candidates found for 'id' type 'speaker::Speaker' Some are 'echo_speaker', 'echo_speaker_kitchen'.
• on line 77: Too many candidates found for 'id' type 'microphone::Microphone' Some are 'echo_microphone', 'echo_microphone_kitchen'.
• on line 90: Too many candidates found for 'id' type 'speaker::Speaker' Some are 'echo_speaker', 'echo_speaker_kitchen'.

There are no other occurrences of the word "speaker" or "microphone" in the conf yaml (and I'm not including other yaml files).

I'm assuming most of this config is default, and the only things I care about are forcing pin 21 for the speaker (line 11) and redirecting audio to my media player (lines 45-52).
